To alt' whom it may concern:

Be it known that I, FREDERICK I. JOHN- SON, a citizen of the UnitedStates, residing in Fitchburg, in the county of Worcester and State ofMassachusetts, have invented an Improvement in Automatic Pistols, ofwhich the following description, lin connec# tion with the accompanyingdrawings, is a specification, like letters'on the drawings "said breechblock being connected with an inertia member or recoil piece, which iscontained in a chamber above and parallel to the barrel, the breechblock and the inert-ia member being formed in a single piece. The

breech block normally lies over the magazine which is contained in thehandle, and is thrown back by the recoil to expose the top of themagazine `and allow a newv cartridge to be forced up in front ofthebreech block to take the 'place of the spent shell which is ejectedthrouglli an opening in the side of he new cartridge is' then pushedinto the barrel in front of the breech-block by the action of a springwhich acts on the recoil-piece to push it forward. The hammer, which ispivotally supported behind the breech block, is provided with a springand is arranged to be operated by the trigrer through. the agency of apush rod whlh extends from an abutment on the hammer forward to thetrigger,` the said trigger acting on said rod to push it back, therebycooking the hammer, the connection between the push rod and the triggerthen being broken so as to allow the hammer to operate. The push rod isnot connected with the hammer, so that in the recoil movement the.hammeris free to move independently of any. movement of the tri ger orpush rod, and merely vfollows the reechblock in both directions.

Figure l is a side elevation, partly in section, of a pistol embodyingtheinvention; Fig. 2 is a similar` view showing the parts in theposition they will reach at the end of the recoil movement.

l ".Ihe breech'blockc, which contains the tiring pin a2 to lire lthecartridge contained recoil piece'or inertia vmember o which is locatedabove the'brg'eech block and contained in a chamber c2 above'andparallel with the barrel. The'sad inertia member or Arecoil piece, 'as'it will be called hereinafter, is acted upon bya spring o3 located inanfextension of the chambery behind the -recoil piece, there being alsoan external linger piece c4 by which the recoil member and the breechblock may be pulled back to allow the first cartridge to pass fromthemagazine into the space in front of the breech block and thence intothe barrel, when the breechblock is moved forward by the spring. Themagazine d is located in the grip or handle d2 directly below the breechblock a, so that when said breech block isdrawn back by hand or forcedback by the recoil, a space is afforded for the topcartridge which isthen pushed forward into thel barrel through the action ofthe s ring c3which restoresl the recoil piece andlbreech block to their normalposition. The hammer e is pivotally suported at e2 below and at the rearof the iireech block and is provided withan engagn rod f which in turnis acte upon by the trigger g. The push rod f is not connected with thehammer, but is meely held by a suitable guideway inengagement with theportion e3, so that the hammer is free to be in the recoil operation. y

The trigger g is provided with a tripping member g2 which engages thefront end of the push rod f,.so that when 4the trigger is pulled', thesaid push rod is forced back throwing the hammer back into tirindisengaging the tripping member g2 `from the push rod f, therebyreleasing the hammer to explode the cartridge. y

The recoil of the explosion throws the shell back, carrying with it thebreech block a and the recoil piece o until the Ishell comes into linewith a lateral opening through the frame of the pistol, (see Fig. 2,)and in its backward movement is acted upon by an ejecting member inthe-usualway. The

space for the inclosed cartridge which is 'pushed up by the spring inthe'magazine, and thengforced forward into the barrel by in the-barrelb' is directly connected with al ing portion e3 to be acted upon by apush spent shell is thus thrown out, leaving a moved back independentlyof said push rod P0 sition, the final movement ofthe trlgger the forwardmovement of the recoil piece through the operation of the spring c3. Thepistol is thus automatically loaded ready to be red by the next movementof the trigger which cocks and releases the hammer. 1aims:

1. In an automatic pistol, the combination with the hammer; wherebythetri'gger is caused to cock and release said hammer; a recoil-operatedv-`extracting and loading device consisting of a movable breech blockhavin an oifsetextended portion, said breech lock and said extended"portion together constitutinga recoil piece; a tubularv guide-way forsaid extended portion parallel to the barrel; and

t a spring located in said guideway behind the extended portion'.

2. In a pistol, the combination with the barrel; of a tubular guide-waylocated above l -a spring operatin of the trigger; means said barrel; arecoil piece comprising a breech block and an oiiset vguide portion,said Aguide portion being located in a tubular guide way above thebarrel, and the breech block extending downward therefrom into alinementwith and behind the barrel; directly on said guide portion; a pivotal ysupported hammer behind the breech block; a push rod acting on saidhammer, but not connected therewith; and a trigger to act upon said pushrod to cock the hammer and release the push `rod when the hammer hasbeen cocked.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
